You should never paint a deck, the paint will peel (unless you live in a very arid climate I guess. The deck may be stained, you can put either oil or latex stain over old oil stain.
All of it. Otherwise the latex stain will seal the surface of the wood and the oil will not be able to penetrate into the wood. Sanding won't remove all of the residue. You'll want to use a paint stripper/stain remover too.

Yes you can if it is a solid stain. However, if you're using toners or semi-transparent stains, you'll want to remove all the water based product prior to applying the oil based stain, otherwise, it will appear blotchy if the water based stain is worn unevenly.

No, you cannot apply oil-based stain over acrylic stain. Oil-based stain will not adhere properly to a surface that has been previously coated with acrylic stain. It is recommended to remove the acrylic stain before applying an oil-based stain for best results.
